> And getting that index through the Rfile reader here Yeah thatis the code I was thinking about. Looked around and found the following code that the tserver uses to find a single split point by inspecting indexes. https://github.com/apache/accumulo/blob/f8bb900ae080fe0f54dfe04f9e1ad8c4dd2e7930/server/base/src/main/java/org/apache/accumulo/server/util/FileUtil.java#L289 The code makes two passes. First it counts the number of index entries. Second read through them again using a merged view of the indexes and takes the count/2 entry. Could possibly do something similar for N entries. Do one pass over the index data to count the entries and then another path to take every count/N entry. The code above falls back to scanning the data in the rfiles instead of the index, would probably need to do that sometime for this use case also. -- This is an automated message from the Apache Git Service.
